      "value": "Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is Prior to 6.1.24. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. Note: This vulnerability applies to Solaris x86 and Linux systems only. CVSS 3.1 Base Score 7.3 (Confidentiality, Integrity and Availability impacts).

Una vulnerabilidad explotable fácilmente, permite a un atacante muy privilegiado y con inicio de sesión en la infraestructura donde se ejecuta Oracle VM VirtualBox, comprometer a Oracle VM VirtualBox. Aunque la vulnerabilidad se encuentra en Oracle VM VirtualBox, los ataques pueden afectar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en una capacidad no autorizada para causar una suspensión o bloqueo repetible frecuentemente (DOS completa) de Oracle VM VirtualBox, así como en una actualización, inserción o eliminación no autorizadas de acceso a algunos de los datos accesibles de Oracle VM VirtualBox y el acceso de lectura no autorizado a un subconjunto de datos accesibles de Oracle VM VirtualBox.
